| Abstract: | We researched the influence of the prior constraints to the station coordinates in the process of GPS baseline solution,then analyzed the field data with the software of GAMIT/GLOBK,and obtained the baseline solutions with different constraints.According to the results,we found the principle of prior constraints in GPS data analysis. |
